Nearly 2 years after masks were required for US travelers, its abrupt end prompts excitement and confusion among passengers

Scenes ranging from excitement to confusion played out across America's airports Monday after a federal judge struck down the Biden administration's mask mandate for public transportation.

Some passengers learned of the Florida judge's decision moments before takeoff, as flight attendants announced that for the first time in nearly two years, masks were optional.

Southwest passenger Pam Eason captured video of the moment a crew member told a plane full of passengers that Southwest had dropped its mask requirement. In the video, passengers can be heard clapping and cheering and one says, "Yay, no more masks!"
